Smith Machine Incline Bench Press

Trains the Clavicular Head.

How to do it

Set an incline bench to about thirty degrees under the Smith machine.
Position it so the bar lands over your upper chest, just below the collarbones.
Set the safety catches below that point.
Lie back, take an overhand grip a little wider than your shoulders, and set your shoulder blades down against the pad.
Unhook the bar, lower it to the upper chest under control, then press back to almost straight arms.
Re-hook the bar at the top before letting go.

Setting the bench steeper than about forty-five degrees. Past that the movement becomes a shoulder press, and the upper chest — the reason for the incline — gets less rather than more.
Positioning the bench so the bar meets the middle of the chest. On an incline the bar belongs high; a fixed line that lands low forces the shoulders forward to meet it.
Pressing the bar toward the face. The fixed path removes that choice, which is exactly why the bench placement has to be right before you lie down.
Arching hard off the pad to turn it back into a flat press. If a flat press is what you want, the flat bench is two feet away.
